False. Formation of a compound is usually exothermic because a Noble Gas configuration forms around each atom. Therefore energy is given off during formation, and the atoms in the compound are more stable.
Of course energy is produced!!! take my word, Chemistry teacher for more then 30 years!!
false, but not sure
Ammonia is a covalent compound. It is a compound of two nonmetals, nitrogen and hydrogen, so the difference in electronegativity is not great enough to cause ionic bonding.
No. CaO is an ionic compound.
In order to break a bond, you need to apply more energy than that holding it together. Energy is released when the bond is broken (the energy that was previously holding the bond together.
It is not a compound word because it is 2 words.Yes it is since hot and dog are 2 separate words with individual meanings placed together to great a new one.
Chemical bonds take a great deal of energy to make, therefore, to create more bonds in a reaction, more energy is required.
yes
A great energy and light is produced by the supernovas. Therefore, a great number of photons is produced.
You need a lot energy to melt the metal compound and then you'd need a great deal of electrical energy to extract the metal from the molten compound.
Thermal energy
a large surface area
the energy comes from the strong nuclear force, which is almost unbelievably powerful.
Solar panels are a great renewable resource from the sun. The energy produced is clean and good for the environment.
I don't see how it could be stored on earth, but obviously a star like the sun stores a great deal of energy, though it is also emitting energy at the same rate it is produced
when the water is flowing over the the dam with high velocity, it acquires great kinetic energy, when this water is used to turn the turbines, this kinetic energy will be converted into electrical energy. so, when the water flows over the dam, hydroelectricity is produced.
Each element has a distinct binding energy - energy which is required to "glue" the individual constituents of an atom (proton, neutron and electrons) together. During nuclear fission, heavier elements decay into lighter elements, thus changing the binding energy of the individual nuclei formed. This minute change releases energy which, when the large number of decays of atoms per second is considered, produces a high quantity of (thermal) energy which is captured by a nuclear fission reactor.

The Great Escarpment is the plateau edge of southern Africa. The Great Escarpment was formed by head water erosion from the rivers.
